TEBRILL W. MCCORMICK, OF BENTON, TEXAS.

BENCH-DOG.

Specification of Letters Patent.

Patented Dec. 27, 191%.

Application filed April 1, 1910. Serial No. 552,760.

To all whom it may concern.

Be it known that I, TERRILL W. McCon- MICK, citizen of the UnitedStates, residing at Denton, in the county of Denton and State of Texas,have invented certain new and useful Improvements in Bench-Dogs, ofwhich the following is a specification.

My invention has relation to work bench attachments and particularly abench dog.

The object of the invention is to provide a dog adapted to be secured toa carpenters work bench comprising a body having a stepped shaped crotchwhereby boards of different widths are received and held in position andthe wedging action reduced to a minimum thus preventing the defacing ofthe end of the board.

Another feature lies in the provision of a stepped portion for eachcombination of widths of boards as for instance one of the steppedportions being sized to receive and hold boards ranging from one andthreefourths inches to one and one-half inches.

A. still further feature resides in the provision of a body adapted tobe secured to a work bench and having a stepped V shaped crotchreceiving a stepped V shaped lining having its upper edge below theupper surface of the body and said lining secured in the body. Thisprovision being made when the body is made of wood or soft material andthe lining of metal whereby the bit of the plane is prevented fromcontacting with the lining.

Finally the object of the invention is to provide means of the characterdescribed that will be strong, durable, eflicient, and easy ofoperation, simple and comparatively inexpensive to construct, and alsoin which the several parts will not be likely to get out of workingorder.

WVith the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in this specification and illustrated in theaccompanying drawings, wherein:

Figure 1. is a perspective view of the dog, Fig. 2. is a longitudinalsectional view on the line 8-1) of Fig. 3, and Fig. 3. is a plan view.

In the drawings, the numeral 1 designates a body preferably formed ofwood or other material not injurious to the bit of a plane.

The body or block 1 has a rounded end 2 and a square end 3 and providedwith a plurality of countersunk screw holes 4, through which screws maybe passed to secure the body to the work bench. It is to be understoodthat other means for fastening the body in place may be employed ifdesired.

The body is provided with a V shaped crotch 5 extending inward from theend 3 centrally of the body. This crotch is stepped and receives astepped lining 6 of comparatively thin metal having a shape fitting thecontour of the crotch 5, but having its upper edge 7 terminating a shortdistance below the upper surface of the body whereby the bit of a planepassed over the dog would contact with the body and be supported abovethe lining and saved from injury.

At its inner end the lining is formed with a lug S fitting in acorresponding recess 9 in the block at the inner end of the crotch. Apin 10 or other fastening is passed transversely through the body andthe lug whereby the lining is fastened in the crotch. As an additionalfastening means, screws 11 are passed transversely through the outerends of the lining into the body.

In the illustration the lining has three.

stepped portions or steps A, B and C. By observing Fig. 3 it will benoted that the vertical walls of these steps are at different angles.This provision is made to accom' modate the different ranges orcombinations of widths, each step receiving a particular range orcombination. For instance step i in receive the ends of boards to beplaned, which vary from two inches to one and one half in ches; whilestep B may? receive boards varying from one and one-half inches toseven-eighths of an inch, and step C boards varying from seveu-eighthsof an inch down. Of course these sizes may be changed as desired by themanufacturer.

It is to be understood that the essential feature of the invention isthe V shaped stepped crotch and it may be employed with various forms ofbench dogs. It is apparent that by providing the steps a longer flatsurface will be presented to the end of the board, than where a straightV shaped crotch is employed, as the angle of the walls of the step willnot be as acute and they will converge more gradually, thus reducing theliability of bruising the end of the board.

What I claim is: I I 1. In a bench dog, a body member having a stepped Vshaped crotch.

2. In a bench dog, a body member having 5 a V shaped crotch, the crotchhaving stepped portions and the Walls of one stepped portion beingdisposed at a different angle to the Walls of the other steppedportions.

3. In a bench dog, a body member having 10 a V shaped crotch, and a Vshaped lining! fitting in the crotch of the body member and having itsupper surface terminating below the upper surface of the body member.

In testimony whereof I have signed my name to this specification in thepresence of 15 two subscribing Witnesses.

TERRILL h/ICCORMICK.
